BREECH-LOADING GUN.

SPECIFICATION forming part of Letters Patent No. 444,574, dated January13, 1891.

Application filed J'anuaryZ, 1890. Serial No. 335,721. (No model.)Patented in France October 27, 1887, No. 186,977; :in Belgium April24,1888,No.81,549; inEngland May 9,1888, No.6,936, and in Italy July 30,1889,1Tgo. 25,915.

To all whom it may concern:

Be it known that we, PTRUS BLACHON and ETIENNE MIMARD, citizens of theFrench Republic, both residing at St. Etienne, in the Department ofLoire, France, have invented certain new and useful Improvements inHammerless Fire-Arms, (Letters Patent for the said invention having beengranted to us in France October 27, 1887, No. 186,977; in Belgium April24:, 1888, No. 81,549; in England May 9, 1888, No. 6,936, and in ItalyJuly 30, 1889, No. 25,915,) of which the following is a specification.

v Our invention relates to improvements in that class of so-calledhammerless fire-arms 7 which are generally used for sporting purposes;and the objects of our invention are, first, to avoid all projectingmovable parts, which frequently cause accidents in handling thefire-arm, and, second, to provide means for facilitating themanipulation of the arm and for indicating automatically if either ofthe barrels is charged with a cartridge. IVe obtain these objects by themechanisms and arrangements illustrated in the accompanying drawings, inWhich- Figure 1 is the rear part of the arm, showing the lock in alongitudinal section and in the position wherein the barrels are lockedand the firing-pin at rest. Fig. 2 is the same sectional view, showingthe barrels elevated and the firing-pin cocked. Fig. 3 is atop view ofthe rear part of the nre-arm with the indicating device, the barrelsbeing partly in sec- Fig. 4 is the butt-end, partly in section, showinga device for automatically stretching the gun-belt close to the stock assoon as the arm is removed from the shoulder. Figs to 11 illustrate thelock parts in details.

The motions for charging the arm are made by means of the pivoted leverc, which laps over the` trigger-guard p and locks the barrels in firingposition by engagement of its notch o2 with a piu fu', passing through asliding piece o. This sliding piece o is guided within a cavity o3, Fig.5, of the lock-frame, and receives in a slot o5 the lugs o6, projectingbeneath the barrels, which it allows to elevate or depress when thesliding piece c is retracted by means of the lever c, Fig. 2.

For locking the barrels the lever c needs to be depressed, whereby thesliding piece u is pushed forward, so that suitable projections o4 o7 ofthe latter will enter the recesses v9 and o8, Fig. 2, of the lugs. Vhilethe sliding piece 'u is retracted bythe lever c, it simultaneously actsby means of its lateral projections t' t" upon corresponding lugs s ofthe traverses E, situated at both sides of the sliding piece c andcarrying at their upper end the firing-pin e for each barrel. At theirlower end each of these traverses is provided with a rod c', extendingwithin a prolongation of the frame beneath the barrels, and beingadapted to receive between the head u and the inwardlyprojecting annularpart of the boring of the frame a helical driving-spring d, which tendsto draw the traverse with the firing-pin into the firing position,Fig. 1. As soon as the lever c is elevated into the position Fig. 2, andthereby the sliding piece o withdrawn against the tension of thedriving-spring d, the .firingpins of both barrels are cocked by the aidof the short arm g of each trigger g, which engages under the action ofa spring f over the projection s of the traverse E, Fig. 2. In thisposition of the firing-pins c the lever c and the sliding piece o may bemoved independently from the action of the spring d and the barrelselevated or depressed, as may be required.

The triggers g, forming with the prolongations g double-armed levers,are pivoted to the frame separate from another in the usual manner. Thetrigger-guard p is provided with suitable cavities 202133, for thereception of the triggers in such a manner that the latter may entirelyrecede within the cavities of the trigger-guard unless the firing-pinshave been cocked before. At the rear end the trigger-guard is alsosuitably formed to receive the rear branch of the lever c, so that onlythe handle c3 will project beyond the triggerguard when the barrels aredepressed.

In order to indicate whether the barrels are charged, the pins tt arepassed through that part of the frame which forms the breech of thebarrels, and they are adapted to recedeV charged with a cartridge R therear end of the latter will press said pins t t', respectively,backward, so that it will appear at the outside of the frame next to thestock of the arm, as shown by the pin t', Fig. 3.

The last part of our invention relates to a device for automaticallystretching the gunbelt, so that the latter may be drawn close to thestock as soon as the arm is taken from the shoulder; and it consists ofa spiral spring 3, wound upon a disk 2 Within the butt of the arm andjournaled between suitable bars l. The free end of said spring 3 ispassed through al guide-plate i and connected to thev gun-belt, so thatthe latter will be stretched straight under the action of the spring;but as soon as the arm is hung over the shoulder by means of thegun-belt the spring 3 is accordingly unwound.

From the foregoing explanation it will be easily understood thatprovisions have been taken to the utmost possible degree and that thesubject-matter of our invention is based upon the idea to obviate anymovable part to protrude from the arm in order to coinbine easyoperation with a 'high degree of safety against accidents in handlingthe arm.

Having now'particularly described and ascertained the nature of ourinvention and in what manner the saine is to be performed, we declarethat what We claim isl. Ina fire-arm, the combination of the pivotedlever c with the sliding piece o, the barrel or barrels of the armhaving lugs@6 underneath to engage with the former, and the firing pinor pins attached to the traverse or traverses E, engaging with thecorrespondingtrigger and actuated by a spring or springs d,substantially as and for the purpose specified.

'2. In combination with cavities located in the gun-stock, atrigger-guard having slits 10 192193 for the reception of the triggersand lever c, the former pivoted in the lower part of the stock and lyinground inside of the trigger-guard, thelatter pivoted within the stock atc and adapted to close round the outside of the trigger-guard,substantially as and for the purpose specified.
